As coronavirus disease 2019(COVID-19)public health restrictions are relaxed,the circulation of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)alongside other respiratory viruses may lead to an increased likelihood of coinfection(1).Older patients face a higher risk of severe outcomes,when infected with multiple respiratory viruses(2).This study highlights the successful recovery of the oldest older adult(≥80 years)from pneumonia caused by the dual infection of human respiratory syncytial virus(HRSV)and SARS-CoV-2.
